I'm still new to this so wait for others to confirm my results. I suspect if my DVD source would have been lossless, the extract audio would also have been lossless using MKVToolNix.

My VOB (dvd source) had lossy compression and the extracted audio had lossy compression as well. 'Lossy' loses a very small bit of information. To convert a video file from one format to another format, the following command is used: ffmpeg -i yourvideoname.mp4 -c:v libx264 outputfilename.wmv. You can change the bit rate to 256Kbps or something else.

Internet research says 'lossless' format is what you want. Here -vn is used to extract audio and -ab is used to save audio as 128Kbps MP3 file. Using Mediainfo., I compared the audio information for the video and audio files separately and they look 100% identical. I bought the software from and it has Windows Media Player 圆4 included, if there a 圆4 version of Windows Media Player, where I can get its standalone installer for Win10 1803?Ĭheers. Most of videos are in mp4 format, but I also have some vob and web video format as well? There are so many many software around to convert or extract audio from video files.īut I need the one which DOES NOT convert at all, and just extract the exact same audio from video file WITHOUT quality loss!

Ffmpeg extract audio and convert
